Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient detection signal by a pressure sensitive sensor by changing the pressing areas of keys for the pressure sensitive sensor according to pushing force. SOLUTION: The pressure sensitive sensor 6 for after-touch is arranged on a keyboard chassis arranged vertically turnably with a white key 2 and a black key 3 and sensor pressing parts 20 and 21 of a peak shape projecting toward the pressure sensitive sensor (6) are formed at the respective rear ends of the keys 2 and 3 at the points corresponding to the pressure sensitive sensor (6). Then, the sensor pressing parts 20 and 21 of the peak shape press the pressure sensitive sensor (6) when the keys 2 and 3 further push the pressure sensitive sensor (6) after ordinary key touch and, therefore, the pressing areas of the sensor pressing parts 20 and 21 for the pressure sensitive sensor 6 may be changed according to the pushing force of the keys 2 and 3. Since the pressure sensitive sensor (6) outputs the detection signal according to the change of the pressing areas, the sufficient detection signal may be obtained by the pressure sensitive sensor (6), by which various kinds of effects may be well imparted to the tones under production and the expressive power of the tones may be further enhanced.

Title: Two-way amplifier of two-wire system
Inventor: FURUYA SENJI
IPC: H04Q3/42
Filed: 1980-03-11
Abstract: PURPOSE:To prevent an excessive output in case when the gain is unnecessary, and always keep a service loss constant, by converting two-wires to four-wires, and negating the excess part by which a service level has exceeded by a prescribed level at the 4-wire output point, by means of a 2-wire side input corresponding to the 4- wire output point. CONSTITUTION:When there is a transmission signal from the S side, this signal is compared with a signal level of the R side as to the relation of magnitude, by the voice signal detection circuit 5, for instance, by decision of S>=R, the variable loss (gain) circuit 3 is set to the gain side, at the same time a loss is given by the same amount by the variable loss (gain) circuit 4, and a prescribed gain (a) dB and a prescribed loss (b) dB are given in the service direction and in the opposite direction, respectively. When the voice service mean level at the 4-wire output point in  this direction exceeds a level which has been set in advance as this gain rises in the service direction, a loss is given to the 2-wire variable loss circuit 8 by the output of the sound detection control circuit 6 for controlling a level. In case when this amplifier circuit has been connected to a trunk line having little loss, a loss is input to the two-wire input part concerned in order to prevent overload of the circuit, which is caused by the amplifying operation.

Title: Magnetic head
Inventor: KANAI KUNIO
IPC: G11B5/265
Filed: 1985-02-20
Abstract: PURPOSE:To obtain a magnetic head which has no void at all on its junction face with satisfactory strength and high reliability, by using a nonmagnetic ceramic member and a magnetic ferrite member put together to each other and forming the mutual diffusion layers with direct fixed phase reactions of both members for junction of these members. CONSTITUTION:The estimated junction faces of a nonmagnetic ceramic member and an Mn-Zn ferrite member are polished up to mirror surfaces and undergo a heat treatment with a contact secured between both surfaces. Here it is required to finish the junction faces of both members as completely as possible in order to facilitate easy reaction (diffusion) with each other. If the heat treatment temperature is low, the fixed phase reactions of both members are obtained just in a limited area. This reduces the intensity of junction. While no linear junction layer is not obtained with an excessively high heat treatment temperature together with generation of voids although the junction intensity is increased. Therefore the heat treatment temperatures are preferably set within a range of 850-1,300 deg.C. The junction intensity is reduced if the thickness of the diffusion layers of both members are too small. While the voids are easily produced with excessively large thickness of said diffusion layers. Thus the thickness of these diffusion layers are preferably set in a range of 5mum-650mu.

Since adhesivity of the cover to the container is good, no liquid leak of product is found, and production efficiency can be extremely improved. Consequently, chocolate having desired syrup can be prepared efficiently.

Filed: 1992-02-19
Abstract: PURPOSE:To eliminate the effect of span error by switching two series contact switches connected in parallel to the input side of each amplifier part receiving the signal from each detection electrode with high impedance using a control means. CONSTITUTION:The positive terminal of an arithmetic amplifier Q4 (Q5) connects to each of a detection electrode 12a (12b) and one end of switch SW3 (SW5), and the negative terminal to the common connection of SW4 and SW6. The switches SW3, SW5 and SW4, SW6 are simultaneously switched on/off, respectively, by the signal from a CPU 20. As for the electrode 12a side, when the switch SW3 is on, the switch SW4 is connected to the common potential point and electrode capacity is discharged after bypassing the input bias current of the amplifier Q4. When the switch SW3 is off, the switch SW4 connects the connection point of switches SW3 and SW4 to the output terminal of the amplifier Q4 to equallize the electric potentials of both ends of the switch SW3. By this, the leak resistance and the impedance of dependence capacity become infinity and electromotive force esa is received by the amplifier Q4 without reduction. It is common for the electrode 12b side.
